Plus I think a "hidden Magnetic attachment" in your glove would make nav coming off the top "interesting"....
to the OP. Obviously AK knows his stuff about gear and has clocked up more that enough suffering miles to find a system that works for him so no doubt it does. Never tried is so can't recommend any types.
For conventional gloves though, I like BD punishers or specialists - fit me well and work for me. I have a pair of OR synthetic insulated mits that I pull over the top on cold belays though.
cheers,
